Scracthed pane

Hello.

Ive been lurking here and making notes on building my first aquarium but unfortunately Im a bit stumped at the moment.

I am planning to building a 900x400x400mm glass tank, 6mm thick. I got the panes and I have checked them out and putting them in pairs, basically rehearsing glue up. Was supposed to glue them together tomorrow.

Then this morning I was pissed to see one of the side pane has a scratch on it. I didnt even realize when that happened. The scratch starts on the edge and ends abt 4 inches down and it ends rather deep. I can definitely catch the whole line with my nails.

Can i get away by putting it on the topside and put euro bracing ard the top perimeter (which i intend to do anyway)?
